* With PWM control, it is not possible to ensure exact parallel running of more than one thermal actuator. If several
actuators are controlled by the same room thermostat, preference should be given to motorized actuators with
On/Off or 3-position control

can be used, refer to the Data Sheets of the selected type of actuator and the following

Engineering notes
See "Reference documentation" below for information on how to engineer the KNX
bus (topology, bus repeaters, etc.) and how to select and size connecting cables
for power supply and field devices.
Mounting and installation
Do not mount on a wall in niches or bookshelves, behind curtains, above or near
heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the
floor.
Mounting ∂Mount the room thermostat on a clean, dry indoor place without direct air flow
from a heating/cooling device, and not exposed to drip or splash water
Wiring See Mounting Instructions M3192 (RDG400KN) or A6V10733804 (RDG405KN)
enclosed with the thermostat.
∂Comply with local regulations to wire, fuse and earth the thermostat
∂Power supply line must have a circuit breaker with a rated current of no more
than 10 A
∂Isolate the cables of inputs X1-M, U1-G0 and D1-GND for 230 V if the conduit
box carries AC 230 V mains voltage
∂Inputs X1-M or D1-GND: Several switches (e.g. summer/winter switch) may be
connected in parallel. Consider overall maximum contact sensing current for
switch rating
∂Isolate the cables of KNX communication input CE+/CE- for 230 V if conduit box
carries AC 230 V mains voltage
∂Disconnect the unit from power supply before removing it from its mounting plate
∂If a KNX bus power supply is connected to the line with communicating
thermostats and a Synco controller, the internal KNX power supply of the Synco
controller must be switched off

Commissioning notes
The room thermostats are delivered with a fixed set of applications.
Select and activate the required application during commissioning using one of the
following tools:
,Local DIP switch and HMI
,Synco ACS
Version 5.11 or higher (for RDG400KN)
Version 10.03 or higher (for RDG405KN)
,ETS
Set the DIP switches before snapping the unit to its mounting plate, if you want to
select an application via DIP switches.
All DIP switches must be set to OFF (remote configuration), if you want to select an
application via commissioning tool.
After power is applied, the thermostat resets and all LCD segments flash, indicating
that the reset was made correctly. After the reset, which takes about 3 seconds,
the thermostat is ready for commissioning by qualified HVAC staff.
If all DIP switches are set to OFF, the display reads NO APPL to indicate that
application commissioning via tool is required.
Each time the application is changed, the thermostat reloads the factory settings
for all control parameters, except for KNX device and zone addresses!
For commissioning, connect the Synco ACS or ETS tool to the KNX bus cable at
any point:
ACS and ETS3 require an interface:
,RS232 KNX interface (e.g. Siemens UP146/02, UP152)
,OCI702 USB-KNX interface
An external KNX bus power supply is required if an RDG.. is connected directly to
a tool (ACS or ETS) via KNX interface.

The thermostat's control parameters can be changed to ensure optimum
performance of the entire system (see Basic Documentation P3192).
The parameters can be adjusted using …
,the local HMI
,Synco ACS
,ETS
∂The control sequence may need to be set via P01 depending on the application.
The factory setting is "Cooling only"
∂Recalibrate the temperature sensor if the room temperature displayed on the
thermostat does not match the room temperature measured (after min. 1 hour of
operation). To do this, change P05
∂We recommend to review the setpoints and setpoint ranges (P08…P12) and to
change them as needed to ensure maximum room comfort and to save energy
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Press the left and right buttons simultaneously for 6 seconds to activate
programming mode, which is indicated on the display with PrOg.
Programming mode remains active until identification of the thermostat is complete.
Assign the device address (P81) via HMI, ACS or ETS.
To deactivate communication, set the device address to 255 (no
exchange of process data).
Use ETS to assign the KNX group addresses of the RDG communication objects.
Each device has a unique KNX serial number inside the plastic housing.
An additional sticker with the same KNX serial number is enclosed in the packa-
ging box. This sticker is intended for installers for documentation purposes.
Disposal
The device is considered an electronic device for disposal in terms of the
European Directive 2012/19/EU and may not be disposed of as domestic
garbage.
∂Dispose of the device through channels provided for this purpose.
∂Comply with all local and currently applicable laws and regulations.
